Logic 1 enables the interrupt generation. After a bus reset, interrupt generation is
disabled, with the values turning to logic 0.
This 1-byte register selects a USB endpoint FIFO as a source or destination for DMA
transfers. The bit allocation is given in

Description
During the DMA transfer, there is a premature termination with
short packet.
DMA transfer is completed with short packet and the DMA
transfer counter has reached 0.
DMA transfer is completed without any short packet and the DMA
transfer counter has reached 0.
